Hello... I have a widescreen DLP projector that can not be moved from its location in the room. As a result of the projector location and my particular room situation, the image from my HDTV cable receiver is too tall in height for my viewing wall. If I purchase a video scaler, will I be able to reduce the overall height of the resulting image coming from my HDTV cable receiver box? I already have a YPbPr auto switch box that switches up to four devices to my projector and also switches the fiber optic digital audio as well. I am looking for a product that will adjust (reduce) the image height from my HDTV cable receiver box. The resolution is already correct, but the overall height is too much for my viewing wall due to room construction. Any recommendations on product(s) that will accomplish this task ???
